STAT1 является членом семейства транскрипционных факторов преобразователей сигналов и активаторов транскрипции[англ.] . STAT1 участвует в положительной регуляции генов по сигналам интерферона либо типа I, типа II, или типа III. В ответ на IFN-γ стимуляцию, STAT1 образует гомодимеры или гетеродимеры с STAT3, которые связываются с GAS (Interferon G amma- A ctivated S equence) промоторным элементом; В ответ на любую IFN-α или IFN-β стимуляцию, STAT1 образует гетеродимер с STAT2, который может связываться с ISRE ( I nterferon- S timulated R esponse E lement) промоторным элементом.[1] В любом случае, связывание элемента с промотором приводит к увеличению экспрессии ISG ( I nterferon- S timulated G enes).
Экспрессия STAT1 в том числе может индуцироваться Диаллилдисульфидом , содержащимся в чесноке.[2]
